libstagefright: Add NULL check for mHFRRatio

Commit 12fa017cb "libstagefright: Enable HFR feature for video recording"
is not yet fully implemented. Camera recording will fail because timeScale
is not calculated properly. Add a simple NULL check to fix.

audio: Added lock during closing of direct output

- Lock is missing when direct output is closed in
  closeOutput_nonvirtual. As mDirectAudioTracks is
  being modified in this function, we need a lock
  here to avoid synchronization issues when it is
  accessed from other methods in AudioFlinger
- Fix is protect direct audio track specific block
  with mLock

libstagefright: Set initial buffer size for H264 codec

For Google h264 decoder, the input port buffer size is
set to 8192 bytes, and for usecases where data source
does not specify input buffer size, there is a crash on
assert when the buffer size is larger than 8192 bytes.

Added change to set input buffer size for H264 to 80k.

stagefright: OMXCodec: free allocated port-buffers if init fails

If an error is encountered while allocating port buffers, init
would fail and buffers already allocated would not be freed.
Move OMXCodec to ERROR state and explicitly stop omx component,
hence forcing free-ing up of allocated buffers.
Also defer setting port-status to ENABLED only after having
moved the component to IDLE and add graphicBuffer to port-
buffers-list only if setBuffer is successful.

NuPlayer: Fix parsing RTSP play response from special server

- In some non-standard server, a different play response will be returned,
  which will cause CHECK failure
- Change in parsePlayResponse(), to get the current track index

stagefright: Omit audio from timelapse recording use-case

Timelapse recording is only valid for video encoding, but audio
is subjected to the same infinite wait. This can result in an ANR
if encoded data is not being produced. Only wait forever in video
use cases.
